    Modelling large deformation and soil–water–structure interaction using the material point method

    Friday, 8 June 2018
    Universitat Politècnica de Catalunya (UPC), Barcelona, Spain

    Large deformation and soil–water–structure interaction problems exist in many environmental and civil engineering problems, such as landslides and slope instabilities, installation of piles in saturated soils, settlement due to consolidation processes, fluidisation and sedimentation processes in submerged slopes, internal erosion in dykes, and scouring around offshore structures.

    The material point method (MPM) is a numerical approach capable of modelling large deformations and, within the framework of the Anura3D MPM Research Community, it has been further developed to cope with soil–water–structure interaction.

    The Anura3D v2017.2 MPM software uses a dynamic explicit MPM formulation. It is capable of simulating 1- and 2-phase materials and free surface water. A fully coupled hydro-mechanical approach is implemented to model the interaction between soil and water phases in saturated porous media. Contact problems can be solved using a contact algorithm. A library of constitutive laws is included as well as an interface for external user defined soil models.

    Tutorials
    Course participants will gain experience as users of the Anura3D v2017.2 MPM software. During training lectures, the attendees will learn first-hand capabilities of MPM by means of a set of practical exercises that will be undertaken following a tutorial specially designed for the course. The tutorial will include the following exercises:

    Location
    Delft University of Technology, Faculty EEMCS (building 36), Lecture hall "Chip"

    Abstract
    The material point method (MPM) is a meshfree mixed Lagrangian-Eulerian method which utilizes moving Lagrangian material points that store physical properties of a deforming continuum and a fixed Eulerian finite element mesh to solve the equations of motion for individual time steps. MPM proved to be successful in simulating mechanical problems which involve large deformations of history-dependent materials. The solution on the background grid is found in MPM by a variational formulation. The integrals resulting from this formulation are numerically approximated by using the material points as integration points. However, the quality of this numerical quadrature rule decreases when the material points become unevenly distributed inside the mesh.

    It is common practice in MPM to adopt piecewise linear basis functions for approximating the solution of the variational form. A problem arises from the discontinuity of the gradients of these basis functions at element boundaries leading to unphysical oscillations of computed stresses when material points cross element boundaries. Such grid crossing errors significantly affect the quality of the numerical solution and may lead to a lack of spatial convergence.

    Dynamic finite element investigation of wave attack on sea dikes: A coupled approach using plate and volume elements

    Location
    Delft University of Technology, Aula Congres Centre (Mekelweg 5), Senate Room

    Abstract
    Approximately 400 kilometres of Dutch sea dikes are protected by bituminous concrete revetments to prevent damage from erosion and repeated wave attacks during storms. The numerical analysis of sea dikes subjected to cyclic wave loading needs to consider the behaviour of the bituminous concrete revetment, and the behaviour of the subsoil including the generation and dissipation of the excess pore pressures, as well as the interaction between the revetment and subsoil. This thesis develops and evaluates numerical methods for investigating this problem, using the dynamic Finite Element Method with the coupling of plate and volume elements.

    In dynamic finite element analysis, the arbitrary selected boundary generates wave reflections which normally causes oscillation problems. Absorbing boundary conditions are therefore adopted to minimise the wave reflection at the artificial boundaries. The effects of the absorbing boundary conditions are investigated in detail for both solid and water phases, and appropriate sets of parameters are recommended.

    Soil–water interaction

    Soil–water interaction exists in many environmental and civil engineering problems, such as landslides induced by rainfall, fluidisation and sedimentation processes in submerged slopes, internal erosion in dykes, scouring around offshore structures, settlement due to consolidation processes and installation of piles in saturated soils. Modelling these processes is challenging due to soil–water coupling and large deformation.
    MPM is a point-based numerical method capable of modelling large deformations and recently, within the framework of the MPM Research Community, it has been extended to cope with complicated soil-fluid interactions.
    This training course focuses on presenting those MPM formulations cable of simulating the interaction between soil and water phases. Two different approaches will be addressed. In the first one, a single set of material points describes the behaviour of saturated porous media understood as a mixture of solid skeleton and pore fluid. The second approach describes the movement of each constituent (i.e. solid and fluid) individually by means of two sets of material points, thereby enabling the simulation of free water and the in and outflow, as well as fluidisation and sedimentation processes.

    A hybrid particle-mesh method for simulating free surface flows

    Date and Time

    Location

    Abstract
    Hybrid particle-mesh methods attempt to combine the advantages of Eulerian and Lagrangian methods: Lagrangian particles are used for the advection, whereas a Eulerian background grid is used for computing the particle interactions. Such a hybrid approach is expected to have several benefits when simulating flows involving free surfaces or material interfaces: the particles can be efficiently used to track the free surface, while the background grid can be used to solve the governing Navier-Stokes equations and impose the incompressibility constraint in a convenient manner. The prospects of these hybrid particle-mesh methods for simulating incompressible fluid flows involving a free surface are assessed in this thesis. More specifically, the feasibility of setting-up a numerical wave flume using hybrid particle-mesh methods is investigated.

  • Géotechnique: "The material point method for unsaturated soils"

    Alba Yerro, Eduardo Alonso, Núria Pinyol
    DOI: 10.1680/geot.14.P.163

    Abstract
    The paper describes a three-phase single-point material point method formulation of coupled flow (water and air) for hydro-mechanical analysis of geotechnical problems involving unsaturated soils. The governing balance and dynamic momentum equations are discretised and adapted to material point method characteristics: an Eulerian computational mesh and a Lagrangian analysis of material points. General mathematical expressions for the terms of the set of governing equations are given. A suction-dependent elastoplastic Mohr–Coulomb model, expressed in terms of net stress and suction variables is implemented. The instability of a slope subjected to rain infiltration, inspired from a real case, is solved and discussed. The model shows the development of the initial failure surface in a region of deviatoric strain localisation, the evolution of stress and suction states in some characteristic locations, the progressive large strain deformation of the slope and the dynamics of the motion characterised by the history of displacement, velocity and acceleration of the unstable mass.

    Samila Bandara, Kenichi Soga
    DOI: 10.1016/j.compgeo.2014.09.009

    Abstract
    This paper presents the formulation and implementation of a numerical procedure based on material point method (MPM) to solve fully coupled dynamic problems that undergo large deformations in saturated soils. The key aspect of this formulation is that it considers two sets of Lagrangian material points to represent soil skeleton and pore water layers. The accuracy of the method is tested by comparing the results to some analytical solutions of consolidation theory. The developed method has been applied to model progressive failure of river levees to illustrate the practical applications. The numerical results show the robustness of the proposed method with regard to large deformations that undergo rapid failure mechanisms.

    Submitted by Alexander Rohe on Tue, 07/10/2014 - 18:18

    Deltares started a collaboration with the universities of Cambridge, Barcelona and Hamburg to establish a research community for the numerical modelling of soil interacting with water. The aim is to further develop a dynamic calculation method, the Material Point Method (MPM), making it suitable to apply for contractors, designers and engineering companies. MPM is used to analyse large deformations and large movements of soil and water, for example to simulate the installation of a piled foundation, the failure of a dike or the sliding of an underwater slope. Further development of MPM will enable us to improve our understanding of the consequences of large soil deformations. The software will be validated using laboratory and field experiments.

    Submitted by Alexander Rohe on Thu, 19/06/2014 - 16:17

    Nederland moet het hebben van kennis en innovatie. Ons land heeft geen overschot aan grondstoffen en de aardgasbaten zullen op termijn achteruitlopen. Ook kent ons land geen massaproductie op basis van lage lonen. De belangrijkste motor voor onze economie is dus kennis, kennis en nog eens kennis. Een mooi voorbeeld van hoogwaardige, door kennis gedreven, productie is ASML, waar geen chips worden geproduceerd maar geavanceerde apparaten waar chips mee worden gemaakt. Gebaseerd op state-of-the-art kennis op dit gebied, ontwikkeld door de Nederlandse fundamentele en toegepaste kennisinstituten. Een ander voorbeeld is het onderzoek in de kwantummechanica, dat mogelijk zal leiden tot de ontwikkeling van de kwantumcomputer die de huidige computers in snelheid en rekenkracht ontelbare malen zal overtreffen. Om tot nieuwe kennis en innovatie te kunnen komen moeten onderzoekers en bedrijven op de beste plek, met de beste faciliteiten en met de beste partners hun werk kunnen doen. Europa maakt die grensoverschrijdende samenwerking mogelijk en de EU stelt daar ook financiering voor beschikbaar. In 2014 is het nieuwe EU-programma hiervoor, Horizon 2020, van start gegaan. Het Zevende Kaderprogramma (KP7, 2007-2013) is daarmee afgerond. Daarvan kan nu de balans worden opgemaakt.

  • Ontwikkeling nieuwe analysetool versterkt positie Europese baggerindustrie

    Submitted by Alexander Rohe on Mon, 26/08/2013 - 12:23

    Marie Curie Industry Academia Partnership & Pathways (IAPP) stimuleert de uitwisseling van jonge en ervaren onderzoekers tussen organisaties uit de niet-commerciële (universiteiten) en commerciële sector (bedrijfsleven). Het Nederlandse kennisinstituut Deltares gaat in het IAPP-project MPM-DREDGE samenwerken met Cambridge University aan een geavanceerde tool voor het analyseren van baggeroperaties.

    Innovatieve simulatie
    Alexander Rohe en Joost Breedeveld (beiden adviseur/onderzoeker Deltares) onderzoeken drie hoofdonderwerpen voor de baggerindustrie: installatie van geocontainers, zettingsvloeiing en erosie. Breedeveld: “Voor het analyseren van problemen waarin zeer grote grondvervormingen in combinatie met water een rol spelen is nog geen geavanceerde tool beschikbaar. Cambridge en Deltares werken daarom samen aan de ontwikkeling en validatie hiervan.” De analysetool is een waardevolle aanvulling op complexe praktijkproeven voor de baggerindustrie, die vaak als duur worden ervaren. Rohe: “Vooral het modelleren van erosie is zeer innovatief en een grensverleggende ontwikkeling.”

    Best of both worlds
    Het IAPP programma ondersteunt het vormen van langdurige, strategische samenwerkingsverbanden tussen universiteiten en de commerciële sector. Breedeveld: “We vullen elkaar perfect aan. Cambridge heeft een van de beste onderzoeksgroepen ter wereld wat betreft grondmechanica. Deltares vertaalt de fundamentele kennis van Cambridge in een bruikbare tool voor de baggerindustrie. Rohe: “Wij leren van hun fundamentele onderzoek, doen modelproeven en hebben contacten met de baggerindustrie.” Breedeveld: “Ook na deze vier jaar willen we met elkaar blijven samenwerken.”
